I will go straight to the point:
overclocked my CPU to 4,3Ghz (200x21,5) at 1.424v (which i think is pretty high!) and I still get errors in OCCT...but not in prime95 (which i read is not that suitable for AMD chips).

My NB and Ram are on default settings :
NB:2000Mhz
Ram:800mhz(11-11-11-28-39) at 1.65v

This is my setup:
AMD fx-6300 http://shop.amd.com/us/All/Detail/Processor/FD6300WMHKBOX
asrock 880gm-le fx http://www.asrock.com/mb/AMD/880GM-LE%20FX/
2x kingston hyperx 4g (khx1600c9d3/4gx) (cant find them anymore and i dont know why...)
Corsair VS450 http://www.corsair.com/en-us/vs-seriestm-vs450-450-watt-power-supply
Gigabyte h7790 1gb (oced to 1200/1600 and stable) http://www.gigabyte.com/products/product-page.aspx?pid=4508#ov

PS:my mobo must be messing with me cause whatever vcore setting i use,it gives a bit more than that...for example the above 1.424v i get it with a 1.400v setting on the bios...Bios and Cpu-z report the same voltage...I also see some variation in vcore readings during testing, Speedfan reports min:0,86 max 1,44
Is that normal?

Any insights/help ?thanks in advance
